Increase cuda memory
When using Unified Memory on Pascal or Volta in CUDA 9 all pages that are accessed by the GPU get migrated to that GPU by default. Although it is possible to modify this behavior by using explicit hints (cudaMemAdvise) for the Unified Memory driver, sometimes you just don’t know if your data is accessed … See more I will focus on a streaming example that reads or writes a contiguous range of data originally resident in the system memory. Although this type of … See more Before diving into optimizations I want to explain what happens when a cudaMallocManaged allocation is accessed on the GPU. You can check out my GTC 2024 talk for more details.The sequence of … See more Instead of having multiple hardware warps accessing the same page, we can divide pages between warps to have a one-to-one mapping and have each warp perform multiple iterations over the 64K region. Here is an updated … See more Since each fault increases the driver’s processing time it is important to minimize page faults during CUDA kernel execution. At the same time you want to provide enough information about your program’s access pattern to the … See more Webtorch.cuda.memory_reserved(device=None) [source] Returns the current GPU memory managed by the caching allocator in bytes for a given device. Parameters: device ( torch.device or int, optional) – selected device. Returns statistic for the current device, given by current_device () , if device is None (default). Return type:
